Effect of SKI-II, CAY10621 and Ceranib 2 on the cell viability determined by WST assay. a FMT-CH-1801 cells were treated with SKI-II, CAY10621 or Ceranib 2 at the indicated concentration for 24 (blue) and 48 (red) hours. Bar represents mean ± SD. p value < 0.05. b FMT-N-1802 (blue) and FMT-AS-1803 (red) cells treated with SKI-II, CAY10621 or Ceranib 2 for 2 days. Bar represents mean ± SD. p value < 0.05. c Annexin-FITC and PI staining after FMT-N-1802 cells treated with SKI-II, CAY10621 or Ceranib 2 for 2 days. The Annexin-FITC positive and PI negative cells represent early apoptotic cells. The Annexin-FITC and PI positive cells represent late apoptotic cells
